Responsibilities:

• Working as a Senior Software Developer at Information Technology and Claims Services department, developing the creation of the new RESTFul Web API service and batch processes, for integrating the claim gathering process of Confidential Claim Management System (ICE) with a third party external Web API solution called ClaimsWire allowing a faster asynchronous transition of data (images, documents and JSON based data). This solution removed the typical slow FTP communication between both companies for sharing files allowing a real time and faster one.
• Helping in the design of the architecture of some important part of the existing system (using Domain Driven Design) such as Host, Service, Domain, Data Access and Data Layer. Implementing unit, integration, functional testing of every main component of the system in an availed environment.
• Creating a client ASP.NET MVC 5 application for monitoring a main RESTful ASP.Net Web API service activity (requests/responses) and logging information. Creating Code UI testing using Selenium Web Driver.
• Working in the development of the Third Party Administration (TPA) Claims Portal in ASP.NET MVC 5 (with a Service Oriented Architecture), which is a self-service portal and has a Business to Business (B2B) capabilities where TPA’s can check the status of their claims, for example: payments, contact, inspection, review comments and upload documents. This project helped to reduce the number of emails received directly by FSAs/ISAs, allowing multiple channels for self-service (Portal and B2B), marketing leverage with new and existing clients. These where some of the accomplished goals: allow automated user registration, user account management, user log in, claim search, claim status, view claim document(s) and upload claim document(s). Creating Design Document with all the business requirements and technical solution.
• Enhancing the functionality of an existing Geographical Information System tool used to search and reassign claims to different adjusters selecting areas in the map. It was developed using Flex and ArcGIS. Creation of a web portal to render in maps geographical information of claims.
• Supporting maintenance for some legacy application created using VB.Net, Classic ASP and Web Form.

This was a Risk Engine mobile app that allows to analyze information about business, addresses and Urls to take important decisions based on the specific report. It has a wide application in different fields like real state, attorney offices, risk assessor and loan offices.
• The architecture used was a Server Oriented Architecture (SOA), a hybrid mobile application as client and a Restful service created in PHP. The revise also needed to call some other external services like MajesticSEO in order perform Backlink Analysis. This project was 100% remote

Responsibilities:

• Working as a Senior Software Developer, developing from scratch an E-Commerce (Online Shopping Site). The site shows the list of products to User/Customer. A user can purchase products and see the previous order history. The application was secured based on user roles, admin is responsible for adding products, categories and approving customer order. It uses payment gateway to do online payment. The application uses a SOA architecture, the service side has a n-tier architecture with extensible approach. The primary goal of this architecture was to share as much code as possible across the web application and further reuse existing code for mobile apps development if necessary. I was developed using the best design patterns and practices. The client application was a web application using ASP.NET MVC 6, AngularJS, Html5, CSS3 and JavaScript with Bootstrap allowing to scale the application for Phone, Tablets, Laptop & Desktop. I was developed using the best design patterns and practices.

A complete application was created from scratch for handling reports. The client application is a Single Page Application using the latest AngularJS framework along with HTML5 and CSS3 using Bootstrap. The application is intended to work on all the major resolutions browsers and devices having a responsive design. For the back-end, a common ASP.Net Web API with RESTFul protocol was created using C# 5.0 which interacts with the SQL server database. The Service and Data Access Layer were developed using Asynchronous Programming increasing the performance per request of the users. It was used OAuth as a token base authorization and cache techniques in the server side. Several load tests were applied satisfactorily.
• Working in the integration of an existing Web API Service in MDCPS with an external third-party WCF notification service called BlackBoard.
• The following actions needed to be taken in every project: taking requirements from the client managers, making high level and low level project design, involved in the scrum process of the team, managing the product backlog items and team velocity in the TFS, construction coding the requirement into language syntax, testing, creation of test cases, testing and bug fixing and production support.

Responsibilities:

• Working as a Software Developer in a team environment, designing and implementing Windows Presentation Foundation (WPF) and Web base Standalone Application (using Asp.Net MVC 4, HTML5, CSS3 and JavaScript) in order to manage the Contacts Information. It was needed to retrieve contacts information from multiple platforms, including IAS (Insurance Automation System), and the Web Portal. A whole WCF Service API was created from scratch with all the system functionality in order to allow access. N-Tire architecture was used in the creation of these two systems, implementing the following layers: Presentation (Windows and Web Base), Service, and Business, Data Access, and Data layer, applying the best design patterns allowing the separation of concerns and the software scalability. Unit and integrations testing were added to the existing project in order to guaranty the quality in the development process.
• The Insurance Automation System (IAS) is the platform on which all future line of business applications of the company will be developed. The current process in IAS is single threaded, meaning that only one user can access a document at a time. On larger documents, this is blocking other user’s requests until the process has completed. This is because IAS is set up to allocate only one content management license. A handled class was developed allowing adding four more users and queuing up requests so it does not lock out other users accessing documents. A very good understanding of threading and asynchronous programing in C# using semaphore class was necessary to success this project.
• Working on different subsystems of Insurance Automation System (IAS), adding new functionalities from the presentation in WPF using the MVVM pattern Services Layer implementing Dependency Injection Container to the Data Layer in SQL Database, creating tables, stores procedures, views and triggers.
